Problem solved, the project loads, time for a coke and a smile? Not always. The next error I ran across was a freaky Webpage Error, Line 56, Error: Unhandled Error in Silverlight Application Code: 2104.
The problem that took me many hours to resolve fixed in less than a minute of your time.
As for the book I am still working on it but with the samples working it is very detailed and covers both WCF webservices as well as WCF RIA web services. Give it a look if you are working on Silverlight 4 like me!
